Complex networked distributed systems are rapidly becoming a feature of many engineering systems.
Their stability, dynamics and reliability has acquired paramount importance.
Control theorists have embraced this challenge through extensive research on the stability of networked control systems, most typically “closed” systems in which a good model of the system is available at design time e.g. [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [4]}.
